b. ADJUSTMENT OF TIME LAG AT FP CONTACT
Wind the shutter. Release the shutter while retaining the tip of the mirror seat (02009) with a finger. As the
mirror seat has tension to flip up at this point, let it move up slowly while retaining it with the finger.
See to it that the FP contact piece A (02023) hits the FP contact piece B (02024) at the instant the front upper
end of the mirror seat (02009) comes to the center height of the hook retainer screw (02091), viz., when the
upper end of the mirror seat is positioned approx. 3 or 4 mm lower than when it has completely flipped up.
Adjustment in this respect should be made by bending (02024) with tweezers as illustrated in Diagram 33. A
shutter speed tester may be also employed for this adjustment.
8. Assembly and Adjustment of Self-Timer
Fasten the eccentric collar (05106) onto the shutter rod (05051) with the eccentric collar retainer screw
(05094). Move the synchro cord (02081) leftward as viewed from the body front, and fix the self-timer
governor (0-08001) to the body proper with a small flat screw, medium, 1.7 x 3.5 and a small saucer screw,
medium, 1.7 x 3.5.
Set the shutter speed dial at 1 sec. Wind the shutter. With the special tool 231 K-H21-A, rotate the wind-up
spindle (08021) counter-clockwise for over 90
°
.
Depress the tip of the release spring (08008) of the self-timer, and the self-timer begins to function. When the
governor operation nears its end, the coupler lever (08005) presses down the aforementioned eccentric collar
(05106), which then presses the shutter rod down.
The reversion of the shutter rod may be considered satisfactory, if it reverses at about the same time when the
2nd curtain travel comes to its end at the set speed of 1 sec. This adjustment, if necessary, is made by turning
the eccentric collar
(05106).
